The famous writer, J. Krishnamurti, gives us an honest insight into the concepts of freedom and discipline. So, according to him, respecting elders is not to be confused with blind obedience. On the contrary, respecting elders is very much essential. Respecting and obeying elders is the usual tradition of our society. We are usually instructed never to question them, and sometimes to follow the same, which is said to be very helpful to us. However, obedience and blind obedience both have different meanings. Obedience is when individuals will have their ethics in their thoughts and check whether the elders' advice meets our views on the topic, and blind obedience is slavery, not freedom. Hence, one can never achieve true freedom through blind obedience, and it does more harm than good.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
